What is a Dual Band WLAN Adapter?

[Cristian_23]

Is this a USB? Or something if it is a USB can I put my files on it? I tried plugging into my computer it makes the sound but I can't seem to find the file anywhere.

It is a wireless network card that supports 2.4GHz and 5GHz.

It comes as USB or PCIe.

You cannot put files on.
